LED descriptions

NOTE:

See

"MSA 2040 SAN" (page 11)

for information about supported combinations of host interface

protocols using Converged Network Controller ports.

1

When in FC mode, the SFPs must be a qualified 8 Gb or 16 Gb fibre optic option described in QuickSpecs.

2

When in 1 Gb iSCSI mode, the SFPs must be a qualified RJ-45 iSCSI option as described in QuickSpecs. The 1 Gb iSCSI mode does

not support an iSCSI optic option.

3

When powering up and booting, iSCSI LEDs will be on/blinking momentarily, then they will switch to the mode of operation.

replication activity.

3

Network Port Link

Active Status

Off — The Ethernet link is not established, or the link is down.

Green — The Ethernet link is up (applies to all negotiated link speeds).

4

Network Port Link Speed

Off — Link is up at 10/100base-T negotiated speeds.

Amber — Link is up and negotiated at 1000base-T.

Fault/Service Required

Amber — A fault has been detected or a service action is required.

Blinking amber — Hardware-controlled power-up or a cache flush or restore

error.

9

Cache Status

Green — Cache contains unwritten data and operation is normal. The

unwritten information can be log or debug data that remains in the cache, so

a Green cache status LED does not, by itself, indicate that any user data is at

risk or that any action is necessary.

Off — In a working controller, cache is clean (contains no unwritten data).

This is an occasional condition that occurs while the system is booting.

Blinking green — A CompactFlash flush or cache self-refresh is in progress,

indicating cache activity.
